The purpose of this study has been to evaluate whether a Low temperature bio-mass dryer could be integrated with the local district heating system in Malå. The aim is to increase the thermal efficiency of the cogeneration plant in Malå, by lowering the temperature of the cooling medium. Another benefit that comes from this is improved combustion efficiency at the power plant, since drying the fuel causes an Increase of the heating value.Simulations has been made in Excel, and with use of linear regression, to find out if it is profitable. Data for this purpose has been supplied by the power company Skellefteåkraft and furthermore SMHI.The result of the Calculations shows that a very efficient bio-mass dryer is needed, if yield of investments should be made possible. An Investment of 4,27 Mkr, in a dryer, could at a such criterium return 60000 kr/year, if the price of the biomass is 190kr/MWh.

In an environment, demanding both innovation and flexibility, higher requirements of competitiveness and productivity is a necessity.

This has contributed to a development of participating working processes in form of groups and teams. The purpose of these communal working processes is that they ought to result in an increased knowledge and understanding among the group members which in turns will generate positive results in the daily work. This drives the search for new knowledge and development possibilities to handle these changed working processes.

Prediktionen av aktieprisutvecklingen har alltid legat i intresse för den finansiella marknadens aktörer. Flera studier har frambringat värdefulla prediktorer för aktieprisutvecklingen. Som en relativt ny prediktor av aktieprisutvecklingen har varians riskpremium rönt uppmärksamhet i forskningsvärlden. Varians riskpremium har i studier visat sig vara träffsäkrare i prognostiseringen av aktieprisutvecklingen än de traditionella prediktorerna som P/E (price over earnings ratio), CAY (consumption wealth ratio) och dividend yield. Varians riskpremium kan även betraktas som ett mått på marknadsimplicerad riskaversion med negativ korrelation till BNP-tillväxttakten.

The aim of this thesis is to give an insight to how work is being pursued within Swedish SMEin the clothing industry. Furthermore we investigate how efforts can proceed withenvironmental questions in a quest for sustainable development and bring clarity in thedifficulties that occur. Through the use of company examples and a description of how theywork we wanted to give stakeholders knowledge in what resources and procedures that areused today on the market. The function of the report is moreover to provide Swedish smalland medium-sized clothing enterprises suggestions and directions of how to advance withinsustainable development.In our theoretical frame we have chosen to administer the theories that we found suitable forour study. Seen from a perspective of sustainability we have thus applied the theories ofstakeholder and legitimacy, an analysis model for a company?s actions in environmentalquestions and the theory of SME which describes a small or middle sized enterprise?s fivecompetitive variables.The empirical frame we acquired for this thesis is presented in three chapters.

The electric car has existed for over a century and producers has tried to commercialize it earlier but has not succeeded. In recent years, however, a change occurred that may be significant for the electric car and it is now to commercialize in the market of passenger cars.

Dagens trend av industriell tillverkning och konsumtion är av linjär karaktär. Material utvinns, blir produkter och hamnar sedan på deponi. Detta examensarbete har tillsammans med Industrial Development Center AB syftat till att skapa en mer hållbar industriell tillverkning inom Skaraborgsregionen, genom att forma en produktutvecklingsprocess i enlighet med cirkulär ekonomi. Cirkulär ekonomi förespråkar att avfall inte får förekomma och att produkter och material ska cirkulera i kretslopp. Projektet bestod därför av en bred förstudie för att samla och utvärdera ett stort område med teorier, processer och företagens ansvarsroller.

The purpose of this paper is to find out which portfolio theory one should use during a financial crisis. We will examine two different portfolio theorys, the Minimum Variance portfolio and the beta portfolio.We have chosen to study two different portfolios, and followed their development during the financial crisis with its start in 2008 and the IT bubble with its start in the middle of 2000.The data has been collected from OMX internet database making it quantitative study. The beta portfolio's objective is to follow the index and the Minumim Variance portfolio´s objective is to spread the risk by investing in stocks with low volatility. By following the two different portfolios, and compare the development to the index, we will be able to determine which theory is most suitable to use during a recession. The studyperiods we chose were both in a recession and it turned out that the most appropriate portfolio to use was the Minimum Variance portfolio because stock in this portfolio tends to be less sensitive to economic fluctuations..

Background and problem: The background to this study is the organizations increased difficulty to retain employees in the organization when more and more employees today choose to do their career in several organizations. The problem to keep the employees in the organization leads to several problems where the loss of experience reduces efficiency and increased risks and cost associated with recruitment are some problems that arise. The problem therefore faced for this study is: How can opportunities for career development within an organization created to get employees to stay over time?Purpose and method: The purpose for this study is to describe how organizations can create opportunities for the development of career that gets employees to stay within the same organization and make their career in this organization. The method used for this study is a qualitative approach where data is collected through semi-structured interviews in a case study.Empiricism: The empirical result have shown there are four factors that an organization should overhaul to create an opportunity for the development of a career that gets employees to stay in an organization over time.

The company Somas, Säffle, has assigned Fredrik Kjellin the project of finding out how ?KVTF DN250?, one of their own valves, reacts on cutting forces under production. They wish to know if and then how much it?s possible to minimize the wall thickness of the valve with neither plastic nor to big elastic deformations caused by processing.The most critical processes have been identified as rough lathing. The study has shown that the marginal for a wall thickness of two millimeters, to fall short of the yield stress in the most critical process, is good.
